TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL GALBliAITH, of Pine Grove Plantation, in the parish of Jefi'erson, and State of Louisiana, have invented a new and useful Composition for Destroying Insects; and I do he 'ehy declare the following to he a full, clear, and exact description thereof. i V

The object of this invention is to provide a, cheap composition which will effectually destroy an insects easily made and applied. l

To accomplish this object I take equal parts, by measure, of quicklime and chloride of sodium or'commou salt. These I pulverize thoroughly, so as to reduce them to an impa-lpahle powder, and thoroughly uiix them I together; I

instantly fatal to worms and insects. Among the insects I liuve thns operated upon are the army-worm or cottoncaterpillar, so destructive to the cotton-plant in the South, the locust or grasshopper, which destroys so vast an ave thoroughly pulverized andiningled, fail to exterminate these pests of vegetation wherever it is applied, This composition is cheap, and can he easily applied. One flour-barrel full will sufiice for forty acres of ground. One man can apply it to from five toteh acres per day. Neither the cost of the materials, which are within reach of every farmer at all times, nor the labor of mixing them, amounts to anything in comparison with the loss to which every farm is annually subjected by the ravages of the insect tribes. Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is The composition above described, when compounded and used in the inanner and for the purpose specified.
